Title: Modified human tissue-type plasminogen activator and its preparation
Inventor: HOTCHKISS ADAIR JOHN
IPC: C12N15/09
Filed: 1987-03-17
Abstract: Human tissue-type plasminogen activators (t-PA) are characterised by having a modified or no carbohydrate structure at amino acid residue 117. Such t-PAs have substantially the same activity and binding characteristics as native t-PA but have an increased in vivo half life. They may be prepared by site mutagenisis corresponding to amino acid residue positions 117 or 118 or 119 or by enzymic removal of most of the carbohydrate at position 117 or native t-PA using an endoglycosidase. The carbohydrate structure at amino acid residue positions 184 and 448 remains unmodified.

Title: Bitumen-rubber-metal fibre or wire based compositions and their use in repairing or surfacing roads
Inventor: MCINTOSH JAMES
IPC: E01D19/06
Filed: 1988-08-26
Abstract: A material for repairing roads and other areas comprises (1) a bitumenous binder, usually rubberised bitumen, which may be mixed with aggregate and chopped glass or other fibres, (2) rubber chips, bound by the binder, and comprising pieces of rubber having a dimension of at least 2 mm, and (3) metal wire or fibre. Suitably the rubber chips and metal reinforcement may be obtained by chopping up old metal reinforced vehicle tyres. The material may be used for patching cracked areas for subsequent treatment with an overlay, the resilient rubberised bitumen being bad bearing and having sufficient tensile strength that reflective cracks are not transmitted to the overlay from underlying concrete having a large coefficient of thermal expansion. Also, the material may be used as a membrane layer covering a base layer or surface. Such a layer may be formed by spreading the binder, possibly also with the addition of strengthening glass fibres, distributing the rubber chips and metal over the binder, and rolling to consolidate.
Patent GB-2212913-A (GB)
Title: Ice warning detector
Inventor: WASHINGTON ROBIN EDWARD CARMIC
IPC: G08B19/02
Filed: 1988-11-28
Abstract: A refractive ice detector comprises a block 11 through which a beam 15 passes from LED1 to photodiode D1 with total internal reflection at surfaces 12 and 13. Any ice or mush builds up at 16 and/or 17, allowing refraction of light out of the beam 15. The reduced intensity is detected by D1, and photodiode D2 detects some of the scattered light. The ratio of the signals from D1 and D2 is determined by ratio circuit 48. LED1 is pulsed by pulse generator 41, and diodes D1 and D2 feed chopper amplifiers. Diode D1 also detects the ambient light level while LED1 is off, allowing adjustment for moderate ambient light and disabling the system for high ambient light. The electronics may be separated from the block 11 by a fibre optic cable. Further sensors may be provided to detect the coefficient of refraction of de-icing fluid and hence the dilution of antifreeze in it, and a temperature sensor T1 may be provided. From the concentration of antifreeze, its rate of dilution, and the temperature and its rate of fall, to time left for an aircraft to reach its icing point may be estimated. <IMAGE>

Title: Packaging equipment
Inventor: CANNELL-SMITH ANTHONY JOHN
IPC: B29C65/82
Filed: 1988-12-19
Abstract: An adhesive joint checking device, which in normal operation is intended to be preceded by or form part of packaging equipment which delivers to the device a succession of roll-wrapped packages, for example, cylindrical packages, whose wrapping is lap-joined along the length of the package; the device comprising means, for example, two contra-rotatable rollers 2 which support the package and rotate it about its longitudinal axis; a wrapping-edge-displacing member comprising at least one protuberance 13 which is so mounted in relation to the rollers or other package-support means that the protuberance or at least one of the protuberances if there are more than one, engages the package at an appropriate position along the adhesive joint, when the package is rotated, in such a way that if the adhesive joint between the over- lapping portions of she packaging is defective, the protuberance will tend to displace the over-lapping portion 15 of the package away from the body of the package; and a detector comprising e.g. photocells in sufficiently close proximity to the displacing member that it generates a reject signal when the amount of thus displaced package material fails to satisfy predetermined requirements. An air jet may assist in lifting said portion 15. The device is disposed along a walking beam type conveyor comprising fixed and moving toothed racks. A first test facilitating comprising a reciprocable pad for detecting incompletely filled packs is followed by package and hot and cold shaping presses, end fold checking station comprising a photocell unit, the adhesive joint checking station, and a weighing station. <IMAGE>

Patent GB-2235891-A (GB)
Title: Stranded electric conductor manufacture
Inventor: BIRBECK THOMAS STANLEY H
IPC: H01B13/02
Filed: 1990-07-06
Abstract: In manufacturing a stranded conductor 1, the cross-sectional shapes of wires 4 being drawn through a lay plate 7 by which the wires are laid helically in a layer around the axis of the conductor are so modified that, on emerging from the lay plate and passing into at least one die 8 downstream of the lay plate, they fit tightly together around a central wire 2 or a preceding layer of helically applied wires. The modified cross-sectional shapes imparted to the wires of each layer approximate to a sector of an annulus. No compacting of the wires is required in the die or dies 8 and, as a consequence, a capstan drawing the wires 4 through the die or dies is not subjected to an undesirable load. <IMAGE>

Title: Reel device
Inventor: RUTHERFORD STEPHEN GRAHAM
IPC: B65H75/14
Filed: 1991-02-06
Abstract: A reel device comprises a housing having a guide for cable being unreeled from the housing. The guide frictionally grips the cable as it is unreeled. The housing is formed, Fig. 6, in two facing cup-shaped lattice parts 31, 32 with a telescoped hub 38. The guide comprises the rims 37 between which the cable passes. The injection moulded resilient plastics of the housing biases the rims towards each other. The hub is formed with a spigot 51 and socket 52 so that reels can be stacked spigot-in-socket. The outer lattice parts of the housing, with rims 6, may be folded aside, Fig. 11, and retained by integral clips 58, to allow winding. The cup-shaped members 31, 32 may be snap-fitted or welded to a separate hub. Alternatively, a cable reel may be fitted on the hub within the cup-shaped members of the device, and located axially by resilient fingers of the device (Fig. 4). <IMAGE>
Patent GB-2255247-A (GB)
Title: Pulse generating circuits
Inventor: HADFIELD KEVIN ANTHONY DEREK
IPC: H04N5/335
Filed: 1991-04-23
Abstract: In a pulse generating circuit each output pulse is produced in response to a counter 2 counting a predetermined number of clock pulses. While the same number of pulses are counted each time, the intermediate count states used to produce consecutive output pulses are different. This reduces or eliminates coherent interference produced by the counter during counting and fed through to the output. When used to generate timing pulses for a video imager, the circuit produces a randomly or pseudo-randomly scattered interference pattern. While the actual amount of interference is unchanged, the distributed pattern is subjectively less objectionable than the visually intrusive regular banded interference pattern produced by a conventional counter which always uses the same count sequence. The intitial count state of counter 2 counting a predetermined number of clock pulses at 15 is set by a circuit 1 receiving line sync pulses 12 to be different for each count cycle. An output pulse is produced by a comparator 4 when the outputs of counter 2 and adder 3 correspond. The counter may be formed by a combination of a memory and latches connected in a feed-back loop. Any of a pluraity of different count sequences stored in the memory is accessed by the selected input to the counter. The output signal is produced by a decoder connected to the outputs of the latches. <IMAGE>
